Renewable energy consumption - financial globalization-tourism nexus with nonlinearity and cross-sectional dependence during Asia's carbon-free transition.

Adopting renewable energy consumption is one of the most important aspects of international efforts to combat climate change, improve energy security, and encourage the shift to a more robust and sustainable energy system. Therefore, the empirics and policymakers worldwide are searching for factors that can promote renewable energy consumption. This analysis intends to investigate the role of financial globalization and tourism on renewable energy consumption in Asia and sub-regions such as Central Asia, East Asia, South Asia, Southeast Asia, and West Asia. The analysis utilized the linear and nonlinear CS-ARDL methods. Long-run outcomes of the linear and nonlinear models confirm that a rise in financial globalization and tourism promotes renewable energy consumption in Asia and all sub-regions. However, the nonlinear model highlights that a fall in financial globalization hurts renewable energy consumption in Central and South Asian regions, and tourism only hurts renewable energy consumption in Asia. In addition, ICT, GDP, and GHG emissions help promote renewable energy consumption. These results suggest that Asian policymakers must increase collaboration in the financial sectors and promote sustainable tourism in the regions to promote renewable energy consumption.

The burden of disease attributable to indoor air pollutants in China from 2000 to 2017.

BACKGROUND: High-level exposure to indoor air pollutants (IAPs) and their corresponding adverse health effects have become a public concern in China in the past 10 years. However, neither national nor provincial level burden of disease attributable to multiple IAPs has been reported for China. This is the first study to estimate and rank the annual burden of disease and the financial costs attributable to targeted residential IAPs at the national and provincial level in China from 2000 to 2017. METHODS: We first did a systematic review and meta-analysis of 117 articles from 37 231 articles identified in major databases, and obtained exposure-response relationships for the candidate IAPs. The exposure levels to these IAPs were then collected by another systematic review of 1864 articles selected from 52 351 articles. After the systematic review, ten IAPs with significant and robust exposure-response relationships and sufficient exposure data were finally targeted: PM2·5, nitrogen dioxide, sulphur dioxide, ozone, carbon monoxide, radon, formaldehyde, benzene, toluene, and p-dichlorobenzene. The annual exposure levels in residences were then evaluated in all 31 provinces in mainland China continuously from 2000 to 2017, using the spatiotemporal Gaussian process regression model to analyse indoor originating IAPs, and the infiltration factor method to analyse outdoor originating IAPs. The disability-adjusted life-years (DALYs) attributable to the targeted IAPs were estimated at both national and provincial levels in China, using the population attributable fraction method. Financial costs were estimated by an adapted human capital approach. FINDINGS: From 2000 to 2017, annual DALYs attributable to the ten IAPs in mainland China decreased from 4620 (95% CI 4070-5040) to 3700 (3210-4090) per 100 000. Nevertheless, in 2017, IAPs still ranked third among all risk factors, and their DALYs and financial costs accounted for 14·1% (95% CI 12·3-15·6) of total DALYs and 3·45% (3·01-3·82) of the gross domestic product. Specifically, the rank of ten targeted IAPs in order of their contribution to DALYs in 2017 was PM2·5, carbon monoxide, radon, benzene, nitrogen dioxide, ozone, sulphur dioxide, formaldehyde, toluene, and p-dichlorobenzene. The DALYs attributable to IAPs were 9·50% higher than those attributable to outdoor air pollution in 2017. For the leading IAP, PM2·5, the DALYs attributable to indoor origins are 18·3% higher than those of outdoor origins. INTERPRETATION: DALYs attributed to IAPs in China have decreased by 20·0% over the past two decades. Even so, they are still much higher than those in the USA and European countries. This study can provide a basis for determining which IAPs to target in various indoor air quality standards and for estimating the health and economic benefits of various indoor air quality control approaches, which will help to reduce the adverse health effects of IAPs in China.

Chronic Care for All? The Intersecting Roles of Race and Immigration in Shaping Multimorbidity, Primary Care Coordination, and Unmet Health Care Needs Among Older Canadians.

OBJECTIVES: Despite the predominance of chronic disease clustering, primary care delivery for multimorbid patients tends to be less effective and often uncoordinated. This study aims to quantify racial-nativity inequalities in multimorbidity prevalence ≥3 chronic conditions), access to primary care, and relations to past-year subjective unmet health care needs (SUN) among older Canadians. METHODS: Population-based data were drawn from the Canadian Community Health Survey (2015-2018). Multivariable logistic regression was performed to estimate the likelihood of multimorbidity, sites of usual source of primary care (USOC), primary care coordination, and multidimensional aspects of SUN. The Classification and Regression Tree (CART) was applied to identify intersecting determinants of SUN. RESULTS: The overall sample (n = 19,020) were predominantly (69.4%) Canadian-born (CB) Whites (1% CB non-Whites, 18.1% White immigrants, and 11.5% racialized immigrants). Compared with CB Whites, racialized immigrants were more likely to have multimorbidity (adjusted odds ratio [AOR] = 1.35, 99% confidence interval [CI]: 1.13-1.61), lack a USOC (AOR = 1.41, 99% CI: 1.07-1.84), and report higher SUN (AOR = 1.47, 99% CI: 1.02-2.11). Racialized immigrants' greater SUN was driven by heightened affordability barriers (AOR = 4.31, 99% CI: 2.02-9.16), acceptability barriers (AOR = 3.11, 99% CI: 1.90-5.10), and unmet needs for chronic care (AOR = 2.71, 99% CI: 1.53-4.80) than CB Whites. The CART analysis found that the racial-nativity gap in SUN perception was still evident even among those who had access to nonpoorly coordinated care. DISCUSSION: To achieve an equitable chronic care system, efforts need to tackle affordability barriers, improve service acceptability, minimize service fragmentation, and reallocate treatment resources to underserved older racialized immigrants in Canada.

[Pollution Characteristics and Ecological Risk Assessment of Antibiotics in Vegetable Field in Kaizhou, Chongqing].

The accumulation of antibiotics in farmland and its ecological risk have become a research hotspot at home and abroad. The objective of this study was to investigate the occurrence and accumulation of antibiotics and their potential environmental and ecological risks in vegetable fields in Kaizhou district of Chongqing country. The occurrence characteristics of antibiotics including tetracyclines, sulfonamides, quinolones, macrolides, and chloramphenicols were detected using experimental analysis. The results showed that there was an accumulation of antibiotics in the vegetable soil, and 18 antibiotics in five categories were detected (0-42.88 µg·kg-1), mainly for tetracyclines and quinolones. The detection rate of quinolone antibiotics was the highest (15.38%-100%), especially for norfloxacin and ofloxacin (100%), whereas the tetracyclines presented the highest concentration (0-42.88 µg·kg-1). The amount of total antibiotics in the vegetable soil was 1.64-233.11 µg·kg-1, whereas different vegetable soils showed the following trend:water spinach soil (89.73 µg·kg-1)>cabbage soil (32.53 µg·kg-1)>pepper soil (32.16 µg·kg-1)>tomato soil (32.13 µg·kg-1)>cucumber soil (26.46 µg·kg-1)>grassland (7.32 µg·kg-1). The correlation results showed that there was a significantly positive correlation between total antibiotic residues and organic fertilizer application (P<0.05) but a significantly negative correlation with soil pH (P<0.05). Quinolones and sulfonamides were negatively correlated with soil water content (P<0.05), whereas quinolones positively correlated with soil available phosphorus and organic matter content (P<0.05). The potential eco-environmental risk assessment results showed that tetracyclines and quinolones in vegetable soil in Kaizhou district had certain ecological risks, of which 62%-92% and 62%-100% of soil samples with quinolones had potential toxicity to soil animals and microorganisms.

Social support, mental health needs, and HIV risk behaviors: a gender-specific, correlation study.

BACKGROUND: The HIV/AIDS epidemic continues to threaten the health and wellbeing of millions in the United States and worldwide. Syndemic theory suggests that HIV/AIDS can cooccur with other afflictions. As close to 20% of US adults live with a mental health condition, it is critical to understand the correlation between HIV risk behaviors and mental health needs, as well as protective factors such as social support in intervening the association between mental distress and HIV risk behaviors. Furthermore, as past research has shown mixed results concerning the function of social support on HIV risks by gender, it is important to conduct a gender-specific analysis. METHODS: To assess the relationship between mental health needs, social support, and HIV risk behaviors, and to assess if social support can be a buffer, weakening the effect of mental health needs on HIV risk, in 2018, we analyzed representative, cross-sectional data from 2016 BRFSS collected from 33,705 individuals from four states in the United States, stratified by gender. Weighted logistic regression analyses, adjusted for age, race, marital status, education, and annual income, assessed the correlation between mental health needs, social support, and HIV risk behaviors. Furthermore, interaction analyses were performed to see if social support modifies the slope of mental health needs as a function of HIV risk behaviors. RESULTS: For both genders, the odds of participating in HIV risk behaviors increase with mental health needs and decrease with the level of social support. Furthermore, social support mitigates the association between mental health needs and HIV risk behavior involvement for males, as males receiving high level of social support have least odds of HIV risk behaviors relative to males receiving low level of social support. Notably, for females, social support does not serve as a buffer against HIV risk behaviors when their mental health needs increase. CONCLUSION: The study contributes to the knowledge base of HIV prevention and highlights the important role of mental health and social support against HIV risk behaviors when developing gender-specific prevention strategies.

"Fewer but not weaker": Understanding the intersectional identities among Chinese immigrant young gay men in Toronto.

Sexual minorities of color in North America are frequently defined as a "double minority" group. Intersectionality theory has inspired investigations into how different forms of marginalization intersect to shape the lives of people with multiple minority statuses. In this constructivist grounded theory study, 18 Chinese immigrant gay men between 18 and 28 years of age participated in a semistructured individual interview to narrate their lived experiences in relation to their intersectional identities. All interviews were transcribed verbatim and analyzed through a constant comparative method. Several themes emerged from the data. First, study participants perceived their sexual identity as either compatible with or irrelevant to their cultural identity and did not experience negotiating conflicts between their sexual and cultural identities. Second, the intersectionality was context-specific. Study participants experienced a certain form of marginalization in the contexts of disclosing their gay identity and finding a dating partner within a gay community. Third, participants considered the label double minority oversimplified and derogatory. They emphasized that their daily lives were in a complex power structure that was constituted by more than two identity categories. The marginalization based on their ethnic and sexual identities weighed differently and should not be understood as simple math. Last, despite carrying the status of minority, these gay men indicated that their intersectional identities served as a source of social support. This study contributes to the knowledge base around intersectionality by uncovering its qualitative nuance and bringing to light its contextual specificity. Practice, policy, and research implications are provided. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Carbon emissions tax policy of urban road traffic and its application in Panjin, China.

How to effectively solve traffic congestion and transportation pollution in urban development is a main research emphasis for transportation management agencies. A carbon emissions tax can affect travelers' generalized costs and will lead to changes in passenger demand, mode choice and traffic flow equilibrium in road networks, which are of significance in green travel and low-carbon transportation management. This paper first established a mesoscopic model to calculate the carbon emissions tax and determined the value of this charge in China, which was based on road traffic flow, vehicle speed, and carbon emissions. Referring to existing research results to calibrate the value of time, this paper modified the traveler's generalized cost function, including the carbon emissions tax, fuel surcharge and travel time cost, which can be used in the travel impedance model with the consideration of the carbon emissions tax. Then, a method for analyzing urban road network traffic flow distribution was put forward, and a joint traffic distribution model was established, which considered the relationship between private cars and taxis. Finally, this paper took the city of Panjin as an example to analyze the road traffic carbon emissions tax's impact. The results illustrated that the carbon emissions tax has a positive effect on road network flow equilibrium and carbon emission reduction. This paper will have good reference value and practical significance for the calculation and implementation of urban traffic carbon emissions taxes in China.

Oral health status in Sichuan Province: findings from the oral health survey of Sichuan, 2015-2016.

To investigate oral health status in the residents of Sichuan Province, southwest China, a cross-sectional study was performed using the latest Oral Health Survey Basic Methods recommended by the World Health Organization. A multistage stratified random cluster-sampling method was used to enroll participants from the following three groups: children aged 3-5 years, adolescents aged 12 years, and people aged 65-74 years. In these three groups, the mean numbers of teeth that were affected by caries were 3.28, 0.86 and 5.13, respectively, resulting in a prevalence of 63.47%, 37.20% and 83.20%, respectively. Relative to the high rate of decayed teeth, the prevalence of fillings was very low in all age groups (0.97%, 7.24% and 5.43%, respectively). In the 12-year-old adolescent group, only 3.61% had good pit and fissure sealing. In addition, the rate of dental fluorosis was 24.80%, and the Community Fluorosis Index value was 0.39. In the elder group, the community periodontal index was 2.92. The prevalence in the elderly of having lost at least one tooth was 75.54%. Additionally, 4.44% of these participants were edentulous. The incidence of dental prosthesis was 51.75%, the proportion with a removable partial denture, a fixed denture, full dentures, dental implants and an informal fixed bridge was 21.59%, 11.45%, 4.64%, 0 and 16.67%, respectively. In this study, 8.2% of the elderly participants were affected by different types of oral mucosal lesions. Among such lesions, recurrent aphthous ulcers were most prevalent (2.69%) and oral lichen planuses were second (1.6%). The conclusion presented in this survey is that oral diseases, especially dental caries and periodontal disease, are frequent and common in Sichuan province, China. Moreover, the treatment rate is very low, and primary prevention and treatment options are therefore urgently needed in this population.

A web-based, health promotion program for adolescent girls and their mothers who reside in public housing.

This study tested a brief web-based, family-involvement health promotion program aimed at drug use, physical activity, and nutrition for adolescent girls, aged 10 to 12 years, who reside in public housing. Separately, girls (n=67) and their mothers (n=67) completed baseline measures online. Following baseline, 36 randomly assigned mother-daughter dyads jointly completed a 3-session, health promotion program online. Subsequently, all girls and mothers separately completed posttest and 5-month follow-up measures. Attrition at posttest and 5-month follow-up measures was 3% and 9%, respectively. At posttest, intervention-arm girls, relative to control-arm girls, reported greater mother-daughter communication and parental monitoring. Intervention-arm mothers reported greater mother-daughter communication and closeness as well as increased vegetable intake and physical activity. At 5-month follow-up, intervention-arm girls and mothers, relative to those in the control arm, reported greater levels of parental monitoring. Intervention-arm girls also reported greater mother-daughter communication and closeness, reduced stress, greater refusal skills, and increased fruit intake. Findings indicate the potential of a brief, web-based program to improve the health of low-income girls and their mothers.

Implementing evidence-based practice: practitioner assessment of an agency-based training program.

Responding to the call for evidence-based practice (EBP) in social work, the authors conducted a multiphase exploratory study to test the acceptability of a training-based collaborative agency-university partnership strategy supporting EBP. The Bringing Evidence for Social Work Training (BEST) study includes an agency training component consisting of 10 modules designed to support the implementation of EBP in social agencies. Qualitative data from post-training participant focus groups were analyzed in order to describe practitioner perceptions of the 10 training modules and trainer experiences of implementation. Based on the findings from this study the authors suggest that the BEST training was generally acceptable to agency team members, but not sufficient to sustain the use of EBP in practice.

Risk model of prolonged intensive care unit stay in Chinese patients undergoing heart valve surgery.

BACKGROUND: The aim of this study was to develop a preoperative risk prediction model and an scorecard for prolonged intensive care unit length of stay (PrlICULOS) in adult patients undergoing heart valve surgery. METHODS: This is a retrospective observational study of collected data on 3925 consecutive patients older than 18 years, who had undergone heart valve surgery between January 2000 and December 2010. Data were randomly split into a development dataset (n=2401) and a validation dataset (n=1524). A multivariate logistic regression analysis was undertaken using the development dataset to identify independent risk factors for PrlICULOS. Performance of the model was then assessed by observed and expected rates of PrlICULOS on the development and validation dataset. Model calibration and discriminatory ability were analysed by the Hosmer-Lemeshow goodness-of-fit statistic and the area under the receiver operating characteristic (ROC) curve, respectively. RESULTS: There were 491 patients that required PrlICULOS (12.5%). Preoperative independent predictors of PrlICULOS are shown with odds ratio as follows: (1) age, 1.4; (2) chronic obstructive pulmonary disease (COPD), 1.8; (3) atrial fibrillation, 1.4; (4) left bundle branch block, 2.7; (5) ejection fraction, 1.4; (6) left ventricle weight, 1.5; (7) New York Heart Association class III-IV, 1.8; (8) critical preoperative state, 2.0; (9) perivalvular leakage, 6.4; (10) tricuspid valve replacement, 3.8; (11) concurrent CABG, 2.8; and (12) concurrent other cardiac surgery, 1.8. The Hosmer-Lemeshow goodness-of-fit statistic was not statistically significant in both development and validation dataset (P=0.365 vs P=0.310). The ROC curve for the prediction of PrlICULOS in development and validation dataset was 0.717 and 0.700, respectively. CONCLUSION: We developed and validated a local risk prediction model for PrlICULOS after adult heart valve surgery. This model can be used to calculate patient-specific risk with an equivalent predicted risk at our centre in future clinical practice.

[Study of multi-factor cognition evoked by binocular disparity].

It is the aim of studies in cognitive process to understand how the impressive cognitive capacity of the human mind is uninterruptedly developed and how the process is controlled. We have been focusing attention on the central question with stereoscopic research. A multi-channel EEG data acquisition system is constructed for cognition studies which not only works perfectly in the EEG collection and signal processing of stereoscopic visual evoked potentials(VEP) but also is suitable for investigative and clinical use. We have identified the fact that the processing of stereoscopic depth information is done in the cortical advance functional areas with labeled characteristic signaling of the depth related VEP and the results were shown to be of no difference when compared with the ones of other investigations. We believe, the stereoscopic depth cognition is both a dynamic multi-factor processing process and a consequence of depth perception in advanced cortical areas through biological feedback to the whole process of visual signal processing. It is our novel and significant supposition in the psychophysical study, and the experimental results of the VEP are presented in this article.
